When Should I Replace My Air Intake Hose? - The intake tube is the hose that connects the air filter box to the intake manifold. It delivers filtered air to the engine, ensuring a proper air-fuel mixture for combustion. If your car is making strange noises, won't start, the check engine light is on, engine performance has decreased, emissions have increased, and idling is difficult or erratic, you may need to replace your air intake tube.
